+====== IPv6 via DTAG ======
+===== Goal =====
+  * Get /56 from DTAG (''%%2001:db8:1234:56::/56%%'')
+  * Use one /57 to carve out /64s for local interfaces (''%%2001:db8:1234:5680::/57%%'')
+  * Delegate the other /57 to another router (''%%2001:db8:1234:5600::/57%%'')
+===== Prerequisites =====
+  * PPPoE configured, interface name ''%%pppoe-dsl%%''
+  * Delegation for /57 on ''%%ether1%%''
+===== Set up DHCPv6 client =====
+    /ipv6 dhcp-client add allow-reconfigure=yes default-route-tables=main interface=pppoe-dsl pool-name=telekom-v6-dyn pool-prefix-length=57 prefix-hint=::/56 request=prefix
+Do **NOT** set ''%%add-default-route%%''! It will mess up your RAs and announce also the /56, then deprecate it before announcing the real prefix.
+===== Set up local /57 pool =====
+    /ipv6 pool add from-pool=telekom-v6-dyn name=local prefix=0:0:0:80::/57 prefix-length=64
+===== Delegate other /57 =====
+    /ipv6 dhcp-server add address-pool=telekom-v6-dyn interface=ether1 lease-time=30m name=router prefix-pool=telekom-v6-dyn
+===== Assign prefix to interface =====
+Just assign an address from the pool, this will start RAs for that prefix on that interface
+    /ipv6 address add address=::49:0:0:0:1 from-pool=local interface=ether1.201
+This will assign ''%%2001:db8:1234:56c9::1/64%%'' (0x80 + 0x49 = 0xc9) to ''%%ether1.201%%''.
